Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to an ultra-thick waterside exterior wall structure and a construction method in an artificial island environment. Background Art

[0002] In the specific artificial island environment, there are cofferdams around the site during the construction phase to facilitate the flow of people and vehicles in and out. The cofferdams will be removed in the later stage, and the outer wall of the basement will be directly in contact with the river, with a immersion height of four meters or more;

[0003] Because the water-facing exterior wall needs to have strong anti-seepage and anti-erosion functions, the exterior wall is far away from the crown beam and the side slope. Therefore, the crown beam and the side slope cannot be used to support and fix the concrete formwork of the exterior wall protective layer. Only one-sided formwork can be formed. However, since the outline of the exterior wall is basically arc-shaped and the height of the exterior wall is 12-15m, it is difficult to support the formwork and prefabricated arc formwork is required, which is costly and takes a long time to complete. In addition, in order to achieve excellent anti-seepage and pressure resistance, it is impossible to install water-stop screws through the wall, which makes construction inconvenient. Summary of the Invention

[0004] The purpose of the present invention is to provide an ultra-thick waterfront exterior wall structure and construction method in an artificial island environment to solve the problems raised in the above background technology.

The spacer support assembly includes a composite plate, a spacer rod and a compression block. The first steel bar and the second steel bar are clamped and fixed by the composite plate and the compression block, and one side of the spacer rod is in contact with the outer wall of the building.

[0009] Preferably, a fertilizer trough is opened on the ground near the outer wall of the building, and a ring beam is cast in the fertilizer trough. The lower ends of several first steel bars are vertically inserted into the ring beam, and the upper ends of the first steel bars are arranged in a U-shaped structure. One side of the upper end of the first steel bar passes over the increased layer and is anchored in the outer wall of the building, and a spacer is provided between the side of the first steel bar passing over the increased layer and the waterproof layer.

[0010] Preferably, two side blocks are symmetrically provided on one side of the combined plate, a horizontal combination groove is horizontally opened in the center of the two side blocks, two supporting springs are symmetrically provided at the upper and lower ends of the two side blocks, and the first steel bar is vertically located between the two side blocks.

[0011] Preferably, the second steel bar is horizontally placed on one side of the compression block, one side of the second steel bar is in contact with the first steel bar, and both sides of the compression block are horizontally inserted into the horizontal combination grooves of the two side blocks.

[0014] Preferably, one side of the spacer rod is provided with an external thread, the spacer rod is provided with a control nut through a movable sleeve of the external thread, the control nut is provided with an anti-slip ring on the side close to the combined plate, and a self-rotating sleeve is rotatably sleeved on the anti-slip ring.

[0015] Preferably, a pull rod is horizontally provided on one side of the self-rotating sleeve close to the combined insertion rod, and the two combined insertion rods and the two pull rods are arranged relative to each other and horizontally staggered.

[0016] Preferably, a hanging rod is horizontally provided on one side of the pull rod close to the combined insertion rod, a hanging groove is opened on one side of the combined insertion rod, and the hanging rod of the pull rod is inserted into the hanging groove of the combined insertion rod.

[0017] A construction method for an ultra-thick waterfront exterior wall structure in an artificial island environment comprises the following steps:

[0018] Step 1: Build a raised floor on the upper end of the building's exterior wall, so that the raised floor is higher than the lower edge of the planting top plate above the building's exterior wall, and apply a waterproof layer on the water-facing surface of the building's exterior wall and the raised floor;

[0019] Step 2: After the waterproof layer is constructed, a fertilizer trough is set up inside the raised floor, the lower end of the first steel bar is inserted into the ring beam, and the upper end of the first steel bar is anchored into the inner side of the building's exterior wall;

[0020] Step 3: Carry out the construction of the first steel bar and the second steel bar, and use the method of combined plate and compression block in the place where the risk of deformation of the first steel bar is relatively large to compress and fix the first steel bar and the second steel bar. At the same time, the combined plate is in contact with the outer wall of the building to maintain the gap between the first steel bar and the outer wall of the building. When the first concrete layer, the second concrete layer and the third concrete layer are sprayed in the later stage, the structural strength of the wall is improved. During operation, the spacer rod is in contact with the outer wall of the building, and the first steel bar is placed between the two side blocks of the combined plate. The compression block is taken and inserted horizontally into the horizontal combined grooves of the two side blocks. At this time, the two combined insertion rods pass through the combined plate and are hung with the hanging rod on one side of the pull rod of the self-rotating sleeve through the hanging groove. Then the control nut is threadedly rotated to make the control nut pull the self-rotating sleeve, the combined insertion rod and the compression block to move, thereby compressing and fixing the first steel bar and the second steel bar.

[0021] Step 4: Spray the first concrete layer, the second concrete layer and the third concrete layer in sequence. The base surface is waterproof material. The first concrete layer is sprayed with special cement mortar, the second concrete layer is sprayed with 05 stone concrete, and the third concrete layer is sprayed with fine aggregate concrete.

[0022] Step 5: Monitoring and adjustment of the spraying process: Real-time monitoring of the thickness and strength parameters of the sprayed anchor, regular inspection of the quality of the sprayed anchor, including spot checks of the quality of the raw materials, the strength of the sprayed anchor samples, adhesion and other indicators; recording and processing of abnormal data and unqualified raw materials to ensure that problems are resolved in a timely manner.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] By setting a ring beam in the fat trough on the bottom side of the building's exterior wall and raising the top of the building's exterior wall to set a heightened layer, the first steel bar is positioned and fixed by the ring beam and the heightened layer during concrete construction, avoiding the problem of being unable to set water-stop screws and the inability to construct due to the formwork fixing point being far away. Then, the water-facing wall is constructed by layered spraying concrete. In addition, when constructing the first steel bar, in conjunction with the interval support assembly, a support member far away from the building's exterior wall can be set at a position where the first steel bar is easily deformed, thereby improving the strength of the temporary concrete structure, reducing the cost, and shortening the construction period.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Please see the attached Figure 1-7 , this application provides the following technical solutions.

[0035] Embodiment 1: An ultra-thick water-facing exterior wall structure in an artificial island environment includes a building exterior wall 1, a height increase layer 2 is provided on the upper end of the building exterior wall 1, a waterproof layer 5 is laid on the side of the building exterior wall 1 and the height increase layer 2 close to the water body, and a first concrete layer 8, a second concrete layer 9 and a third concrete layer 10 are vertically sprayed in sequence on one side of the building exterior wall 1 located on the height increase layer 2. The setting of the height increase layer 2 facilitates the subsequent concrete construction and can be used as a barrier for the planting top plate.

[0036] A steel mesh assembly is provided to improve the strength of the water-facing concrete structure. The steel mesh assembly includes a plurality of first steel bars 6 and a plurality of second steel bars 17. The plurality of first steel bars 6 and a plurality of spacers 7 are cross-staggered and placed in the first concrete layer 8, the second concrete layer 9 and the third concrete layer 10. A fertilizer trough 3 is provided on the ground near the exterior wall 1 of the building. A ring beam 4 is cast in the fertilizer trough 3. The lower ends of the plurality of first steel bars 6 are vertically inserted into the ring beam 4 respectively. The upper end of the first steel bar 6 is provided in a U-shaped structure. One side of the upper end of the first steel bar 6 passes over the added layer 2 and is anchored in the exterior wall 1 of the building. A spacer 7 is provided between the side of the first steel bar 6 passing over the added layer 2 and the waterproof layer 5. The provision of the spacer 7 prevents the first steel bar 6 from wearing and damaging the waterproof layer 5 during the construction process. The cooperation of the added layer 2 and the ring beam 4 can provide fixed support for the first steel bar 6. The first steel bar 6 needs to be straightened and derusted before construction.

[0037] In this embodiment:

[0038] Example 2: On the basis of Example 1, a spacing support assembly is provided to prevent the deformation of the first steel bar 6 and affect the strength of the concrete layer after it is close to the building exterior wall 1. The spacing support assembly is provided at the staggered position of the first steel bar 6 and the second steel bar 17. The spacing support assembly includes a composite plate 11, a spacing rod 12 and a clamping block 16. The first steel bar 6 and the second steel bar 17 are clamped and fixed by the composite plate 11 and the clamping block 16, and one side of the spacing rod 12 is in contact with the building exterior wall 1. Two side blocks 13 are symmetrically provided on one side of the composite plate 11. A horizontal combination groove 15 is horizontally opened in the center of the two side blocks 13. Two supporting springs 14 are symmetrically provided at the upper and lower ends of the two side blocks 13. The first steel bar 6 is vertically located between the two side blocks 13. The distance between the two side blocks 13 is the same as the diameter of the first steel bar 6, which facilitates the combination of the first steel bar 6 and the composite plate 11.

[0039] The second steel bar 17 is placed horizontally on one side of the clamping block 16, and one side of the second steel bar 17 is in contact with the first steel bar 6. The two sides of the clamping block 16 are horizontally inserted into the horizontal combination grooves 15 of the two side blocks 13. The side blocks 13 are located in the horizontal combination grooves 15 and are symmetrically provided with a number of constraint grooves 19 at the upper and lower ends. The upper and lower ends of the clamping block 16 are symmetrically provided with a number of constraint bars 18, and one side of the constraint groove 19 is inserted into the constraint bar 18. When the clamping block 16 is inserted into the two side blocks 13, the second steel bar 17 and the first steel bar 6 are cross-staggered and abutted. At this time, the constraint groove 19 is inserted into the constraint bar 18, which can prevent the clamping block 16 from arbitrarily detaching from the horizontal combination groove 15 under the elastic downward pressure of the supporting spring piece 14. The side surfaces of the constraint bar 18 and the constraint groove 19 are both inclined surfaces, which facilitates the insertion of the clamping block 16 into the pre-positioning.

[0040] The clamping block 16 is located in the horizontal combination groove 15 and is provided with an L-shaped adapter plate 20 on one side. A combination rod 21 is horizontally provided on one side of the L-shaped adapter plate 20, and one side of the two combination rods 21 is movably penetrated through the combination plate 11. An external thread is provided on one side of the spacer rod 12. The spacer rod 12 is movably sleeved with a control nut 23 through the external thread. The control nut 23 is provided with an anti-slip ring on the side close to the combination plate 11. A self-rotating sleeve 24 is rotatably sleeved on the anti-slip ring. A pull rod 25 is horizontally provided on the side of the self-rotating sleeve 24 close to the combination rod 21, and the two combination rods 21 and the two pull rods 25 are relative to and horizontally displaced. A hanging rod 26 is horizontally provided on the side of the pull rod 25 close to the combination rod 21. A hanging groove 22 is provided on one side of the combination rod 21, and the hanging rod 26 of the pull rod 25 is inserted When the combined rod 21 is connected to the hanging groove 22, the combined plate 11 and the clamping block 16 are independent structures when they are not used together. When the two need to be installed on the side of the first steel bar 6 that may be deformed, the two combined rods 21 are passed through the combined plate 11, and the clamping block 16 pushes the second steel bar 17 to abut against the first steel bar 6. Then the hanging rod 26 is hung with the hanging groove 22. When the control nut 23 is threaded away from the combined plate 11, the clamping block 16 is pulled to clamp and fix the second steel bar 17 and the first steel bar 6, and keep the spacer rod 12 in contact with the building exterior wall 1 to avoid the spacing between the first steel bar 6 and the building exterior wall 1 being too small. The side of the spacer rod 12 in contact with the building exterior wall 1 needs to squeeze the waterproof layer 5, so the end of the spacer rod 12 should be an elastic structure or a contact plate with an enlarged area to avoid damage to the waterproof layer 5.

[0041] A construction method for an ultra-thick waterfront exterior wall structure in an artificial island environment comprises the following steps:

[0042] Step 1: Build a high-rise building 2 at the upper end of the building's exterior wall 1. The height of the high-rise building 2 is 1.5-2.3m, so that the high-rise building 2 is higher than the lower edge of the planting top plate above the building's exterior wall 1. Apply a waterproof layer 5 on the water-facing surface of the building's exterior wall 1 and the high-rise building 2. The waterproof layer 5 includes a waterproof coating layer and a waterproof membrane layer. The waterproof coating is constructed with 2mm thick high-viscosity anti-slip rubber asphalt coating. The outer layer of the coating is additionally coated with a 1.5mm thick self-adhesive polymer modified asphalt waterproof membrane (without tire). The asphalt coating should be sprayed in a "cross" spraying method. The wet film thickness of each spraying should not exceed 1.0mm. Spray three times to ensure a thickness of 2mm. The spraying should be uniform and there should be no exposed bottom or accumulation.

[0043] During spraying, the spray pressure and the reciprocating frequency of the spray gun must be constant to effectively control the coating thickness and ensure that the waterproof layer is formed in one go. A thin, multiple-pass application method is also adopted to ensure uniform spraying and reduce the fluidity of the paint on the facade due to its own weight.

[0044] After spraying a certain area, use a coating thickness gauge to check the coating thickness before laying the membrane. If the thickness is not up to standard or if a part needs to be strengthened, use a trowel to apply some paint and apply it manually. Spraying should be completed in sections or zones, with each zone covering 500 to 1000 square meters.

[0045] After spraying, promptly cover the waterproofing membrane to prevent excessive dust from adhering to the coating surface and reducing the adhesion between the coating and the waterproofing membrane. Draw a baseline according to the shape, size, and specifications of the work surface. Before laying the membrane, carefully calibrate the membrane position according to the baseline. Unfold the membrane and align the long and short sides and overlapping edges according to the baseline. When laying the second membrane after laying the first membrane, the overlap of the long side with the first membrane should be laid according to the overlap guide line on the membrane. The overlap should be at least 100mm wide. When overlapping, ensure that the overlap is clean and dust-free. Use a roller to compact the overlapping edge of the membrane, expel bubbles, and tightly compact and adhere. The membrane should be rolled while laying to remove air from the lower surface of the membrane. Repeat the above steps until the laying operation is completed.

[0046] The waterproof membrane is made to 500mm from the corner of the top plate, and the joints of the membrane are fully coated with rubber asphalt waterproof coating to seal the interface. The top plate corners need to be fixed with fixing nails, and the fixing nails are sealed with waterproof coating.

[0047] Step 2: After the construction of the waterproof layer 5 is completed, a fertilizer trough 3 is set inside the height-raising layer 2, the lower end of the first steel bar 6 is inserted into the ring beam 4, and the upper end of the first steel bar 6 is anchored into the inner side of the building outer wall 1.

[0048] Step 3: Build and construct the first steel bar 6 and the second steel bar 17, and use the combined plate 11 and the clamping block 16 in the place where the deformation risk of the first steel bar 6 is greater, and compress and fix the first steel bar 6 and the second steel bar 17. At the same time, the combined plate 11 contacts the building exterior wall 1 to maintain the gap between the first steel bar 6 and the building exterior wall 1. When the first concrete layer 8, the second concrete layer 9 and the third concrete layer 10 are sprayed in the later stage, the wall structure strength is improved. During operation, the spacer rod 12 contacts the building exterior wall 1, and the first steel bar 6 is placed between the two side blocks 13 of the combined plate 11. Take the clamping block 16 and insert it horizontally into the horizontal combined groove 15 of the two side blocks 13. At this time, the two combined insertion rods 21 pass through the combined plate 11 and are hung with the hanging rod 26 on one side of the pull rod 25 of the self-rotating sleeve 24 through the hanging groove 22. Then, the control nut 23 is threadedly rotated to make the control nut 23 pull the self-rotating sleeve 24, the combined insertion rod 21 and the clamping block 16 to move, thereby compressing and fixing the first steel bar 6 and the second steel bar 17.

[0049] Step 4: spray the first concrete layer 8, the second concrete layer 9 and the third concrete layer 10 in sequence. The base surface is waterproof material. The first steel bar 6 is sprayed with mortar to prevent the sprayed concrete stones from damaging the waterproof material. The latter layer of spraying should be carried out after the previous layer of concrete has finally set, but the interval should not be too long. If spraying is carried out 1 to 2 hours after final setting, the concrete surface should be cleaned with Feng Shui to facilitate interlayer bonding, control the level and uniformity of the sprayed anchor, and ensure that the construction effect meets the design requirements. The first concrete layer 8 is sprayed with special cement mortar to ensure that the exterior wall membrane is not damaged. The second concrete layer 9 is made of 05 stone concrete to ensure the strength of the sprayed concrete. The third concrete layer 10 is sprayed with fine aggregate concrete to ensure the flatness of the exterior wall.

[0050] Raw materials for shotcrete: To ensure the construction quality of shotcrete, the procurement, purchase, inspection and acceptance, and inventory of raw materials must be carried out in accordance with standard procedures, and the concrete mixing must be strictly carried out according to the mix ratio requirements. The measuring instruments of the mixing system must be complete and accurate. The laboratory must monitor at the frequency required by the test procedures. The mix ratio and slump index of shotcrete should be controlled to ensure that the concrete is sprayed onto the slope surface quickly, with little rebound, no flow, and is flat and dense. The aggregate particle size of shotcrete should be controlled below 20mm, and the water-cement ratio should be 0.40-0.50. The mix ratio of shotcrete can be: cement 460: sand 807: stone 948: water 165: early strength agent 50.

[0051] Wind pressure: It should be the wind pressure when the sprayer is working normally. If the wind pressure is too high, the spraying speed will be too high, the concrete will rebound greatly, and the cement consumption will be high; if the wind pressure is too low, the concrete will not be dense.

[0052] Spray direction and distance: The nozzle should be as perpendicular to the sprayed surface as possible, and the deflection angle should be controlled within 20°. Use the spray material to suppress the rebound of the aggregate to reduce the rebound amount. The distance between the nozzle and the sprayed surface should be controlled at about 1.0m.

[0053] The thickness of shotcrete must meet the design requirements, the surface layer must be smooth, and there must be no hollows, cracks, or exposed reinforcement.

[0054] Step 5: Monitoring and adjustment of the spraying process: Real-time monitoring of the thickness and strength parameters of the sprayed anchor, regular inspection of the quality of the sprayed anchor, including spot checks of the quality of the raw materials, the strength of the sprayed anchor samples, adhesion and other indicators; recording and processing of abnormal data and unqualified raw materials to ensure that problems are resolved in a timely manner.

[0055] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
